The controls are a bit... Funky.
It's kinda funny, but the WASD keys all do the same exact thing. IE: Moving you forward.
I also noticed that the camera sometimes won't turn in one direction, especially when you're standing still.
The power outage really needs some reworking. Either by having more guide lights, or the ability to use your flashlight still.
Truth be told, I don't understand the logic behind a flashlight that stops working when the building's power goes out. Especially if you also have to charge it.
You can't see anything at all if the power goes out, so there's pretty much nothing you can do but stand around and wait for the animatronics to get you. Except the animatronics don't go everywhere, so if you get stuck in a spot where they don't go and you can't see anything, literally the only option you have is to Alt+F4. Which is extremely disengaging.
Also, as a personal gripe, I once met a man who'd recently had surgery on both of his hips, and he still walked faster than the catboy security guard here.
